SANZENBACHER            METHOD FOR THE DIRECT REDUCTION OF IRON USING GAS FROM COAL     ABSTRACT     A method for direct reduction of iron in a shaft reduction furnace.          Spent gas from the furnace is upgraded in reductant by removal of CO2 and water to form an upgraded gas.  A fossil fuel is gasified to produce a hot gas which is tempered with a first stream of upgraded gas.  The mixture is desulfurized by reaction with lime to produce hot desulfurized gas.  A second stream of upgraded gas is heated and  m;xed with the hot desulfurized gas to produce hot reducing gas,

Abstract: TITLE                     MARKING APPARATUS            ABSTRACT OF THE DISCLOSURE      A marking head rotatably supports a plurality of marking wheels that are supported for rotation by a shaft positioned in the marking head.  The marking wheels each include a periphery with a plurality of marking characters positioned thereon for marking plates, name plates, identification plates and the like with a preselected marking character.  A preselected marking character for each wheel is positioned in marking position by rotating the respective marking wheel through a preselected angle which is preferably the angle for advancing the next adjacent char-ater into marking position.  A plurality of fingers are rotatably positioned on a shaft for engaging a ratchet portion of a respec-tive wheel.  Each finger is rotatably supported to selectively move into and out of engagement with the respective ratchet portion by operation of an air actuated plunger abutting the end of the finger. After selected fingers are moved into engagement with the corres-ponding marking wheels, the shaft supporting the fingers is moved downwardly in an arcuate path through a preselected angle to move the fingers through a corresponding angle and thereby rotate the marking wheels engaged by the fingers through a preselected angle. The engaged marking wheels are turned so that the marking characters or indicia positioned in marking position are moved out of marking position and the next adjacent characters on the periphery of the marking wheels are moved into marking position. Once the selected indicia are moved into marking position, the fingers are disengaged from the respective ratchet portion and rotated backwardly in an arcuate path to their initial position.

Abstract: ABSTRACT OF THE DISCLOSURE:            A rectangular-type color cathode ray picture tube includes a phosphor-screen-bearing faceplate with a rearwardly extending flange and a substantially rectangular shadow mask assembly.  The mask assembly is suspended adjacent to but spaced from the faceplate by a plurality of leaf springs spaced about the periphery of the mask assembly.  The plane of each spring is substantially parallel to the center axis of the tube.  An end section of each spring is anchored to the mask assembly, and a distal end is detachably engaged to an associated stud protruding inwardly from the faceplate flange.  The engagement is by movement of the distal end toward and away from the tube axis.  Each spring is characterized by having an intermediate active section which in its unloaded state extends away from the mask assembly in a predetermined precurvature.  The spring is deflectable through a first position wherein it is engaged with the stud, to a limit position toward the mask assembly wherein the spring provides maximum clearance for the stud and all portions of the spring for facile mask assembly insertion and removal.  The precurvature is such that the spring, upon deflection, self-straightens to a substantially planar configuration either upon engagement with the stud wherein the mask assembly has enhanced immunity to shock-induced dislodgement or mispositioning; or the spring approximately self-straightens at the limit position preventing possible overstressing of the spring or at a compromise position intermediate to the first position and the limit position.

Abstract: ABSTRACT     An alternating current electrical machine construction in which a primary winding is modified to create transient electromagnetic conditions for example by having at least two distinct values of pole pitch.  In a linear induction motor (Figure 8a) a first pole-pitch portion (STAL) is followed by a second portion (STAA) of shorter pole-pitch.  When an inductively coupled solid rotor passes from first to second rotor currents "memorised" from the first, propulsion, section cause current in the second, recovery section.  This current can be of unity or leading power factor.  Appropriate winding design permits the operation of the machine using an inverter (LCIA) without making provision for reactive power supply. Part of the machine winding, the recovery section, functions as an asynchronous condenser (ASCA) to cope with the reactive power components (Figure 8b).  In a cylindrical machine the winding modification can provide transient creating pole or part-pole windings controlling the quadrature flux component.

Abstract: Abstract of The Disclosure Process and apparatus for extracting an organic liquid from an organic liquid solute/solvent mixture.  The mixture is contacted with a fluid extractant which is at a temperature and pressure to render the extractant a solvent for the solute but not for the solvent. The resulting fluid extract of the solute is then depressurized to give a still feed which is distilled to form still overhead vapors and liquid still bottoms. The enthalpy required to effect this distillation is provided by compressing the still overhead vapors to heat them and in directly to heat the still feed.  The process is particularly suitable for separating mixtures which form azeotropes, e.g., oxygenated hydrocarbon/water mixtures.  The energy required in this process is much less than that required to separate such mixtures by conventional distillation techniques.

Abstract: ABSTRACT         SWITCHING CIRCUIT FOR A REMOTE CONTROL SYSTEM         The switching circuit couples an appliance to a power main (LN) via remotely controllable switching means and is operable to change the state of the switching means in response to a manual double switching of the appliance power switch so that the appliance can be manually switched ON after is has been remotely switched OFF.  A capacitor (CAP1) generates from the mains voltage an alternating current signal of a phase differing from that of the mains voltage by an amount dependent on the external impedance across the output.  The switching circuit monitors this phase difference and changes the state of the switching means if it detects two phase difference changes exceeding a predetermined value in opposite senses within a pre-determined time period, this being indicative of a manual double switching of the appliance power switch.  The switching circuit does not operate spuriously for thermo-statically controlled appliances nor in response to noise spikes.
